WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 578,616, dated March 9,1897. Application filed November 27, 1896. Serial No. 613,676. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE M. WHITE, a citizen of the United States,residing at J efferson, in the county of Greene and State of Iowa, haveinvented certain new and useful Improvements inWeather-Strips,of whichthe following is a specification.

This invention relates to weather-strips, and particularly to aweather-strip for hinged or swinging doors or windows, and pertainsespecially to the class of weather-strips operated by a projection orroller upon a door or window jamb to close said strip hard against thesill thereof with the closing of the door or window.

The object of the invention is to provide a new and improved means forhousing an apron or sleeve at the bottom of a door and to provide apeculiar and novel device to make an adjustable spring-hinge connectionbetween the housing and the said leaf or apron.

A further object of the invention is to provide a spring connectionbetween the weatherstrip leaf or apron and the housing therefor whichshall be attached only at one end of the said two specified parts.

A still further object of the invention is to provide an operating meansfor the said apron consisting of a roller journaled to the doorjamb andadapted to engage the apron and gradually close it down upon thedoor-sill automatically with the closing of the door.

Other advantages and improved results accruing from the specialconstruction and arrangement of the several parts of my invention willbe hereinafter disclosed in the specification to follow.

The invention consists in the novel construction and arrangement ofparts and resides, essentially, in a spring-hinged connection betweenthe weather-strip housing and the apron.

In the accompanying drawings, forming part of this application, Figure 1is a perspect-ive view of a door provided with my weather-strip and theroller journaled in the door-jamb for operating the same. Fig. 2 is alongitudinal sectional, view. Fig. 3 is perspectiveview, partiallybroken away, showing the-apron thrown down as when engaging a door-sill.Fig. 4 is a perspective view,par-

tially broken away, of the housing. Fig. 5 is an enlarged perspectiveView of part of the tube or barrel shown in Figs. 2 and 3, except thatthe slotted end of the apron terminates short of the end of the tube.Fig. 6 is a sectional view showing a modified form of spring adjustment.

The same numeral references denotethe same parts throughout the severalfigures of the drawings.

The housing 1 is secured to the bottom of a door 2 in the usual manner,and a roller 3 is journaled at 4: to the door-jamb 5 in a horizontalplane with the housing. This housing 1 consists of a strip of metal orother suitable material like unto an ornamental molding, having acentral bore 6, with a continuous longitudinal opening or mouth 7 fromsaid bore sm a1 ler than the latter, a vertical straight back 8, anoverhanging lip 9, and an upwardprojecting lip 10. p

The curved leaf or apron 11 is formed in the same piece with the barrel12, both being composed of a single piece of sheet metal. The barrel hasa set-screw 14 for securing the keeper 15 therein. A similar keeper 16,having a rim or flange 17 inclosing one end of the barrel, a series ofapertures 13, and a cavity or slot 13, is adjustably secured in theouter casing of the housing by an adjusting pin 16. The outer end of thebarrel is oscillated upon the keeper 16. The inner surface of the flangeor rim 17 forms a bearing for the said barrel end and the outer surfaceabearing for the outer end of the apron 11, having a slot 18, thusmaking a perfect and effective bearing between the housing,tube, andapron. Said slotted apron end may terminate short of the end of the tubeor barrel 12, as shown in Fig. 5, so that said apron end will not strikethe door-jamb in operating the door.

The spring 19 is preferably formed of sheetsteel, although for largedoors it may be composed of thicker angular metal. The ends of thespring are formed integral with or secured, respectively, to the keepers15 and 16, and the tension of the spring is increased or diminished, asdesired, by inserting a suitable tool, such as a screw-driver or similarimplement, in the cavity or slot 13*, removing the adj ustable pin 16,and turning the keeper 16 until one of its apertures 13 registers with alike aperture in the housing When the said pin is replaced.

A modified form of spring adjustment is shown in Fig. 6, the tube 24having a series of apertures 25, engaged by a set-screw 26, Whichsecures one end of a long spring 27 to the keeper 28 and the latter tothe tube. The other end of the spring is secured to an outer keeper 29,permanently fixed to the housing 30. To change the tension of thisspring, the keeper 28 has simply to be moved back and forth, whichincreases or diminishes the length of the spring between the keepers.This change of spring tension is highly essential, because it has beenfound in this class of spring-hinged Weather-strips that the continuousstrain upon the spring Will Weaken and seriously impair its purpose tosuch an extent that it Will not return the apron into its housing clearof the door-sill, Whereas in accordance With the means here describedfor changing the tension of the spring such obstacles and objections areWholly avoided, giving the spring longer life and insuring always thecertain return of the apron.

The roller is provided in lieu of any other device for the throw down ofthe apron, because the latter is not Worn or otherwise disfigured bycontinuous contact With the roller, and the latter is not liable to theWear and tear of the apron and cannot be readily broken or disabled.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. I11 a Weather-strip, the combination of the housing, with the barrelinclosed by the housing and having an apron, the keeper secured to oneend of the housing and forming a bearing for the barrel, and a springhaving one end connected to the barrel and the other end attached to thesaid keeper, as set forth.

a suitable housing, and a barrel operated in the housing and having anapron, of means for operating the barrel comprising a platespring havinga lug or keeper at each end, one of said keepers being secured upon theinside of the barrel and the other keeper adjustabl y attached to thehousing and forming a bearing for the barrel, as set forth.

3. The combination With a Weather-strip housing having a centrallongitudinal bore, and a mouth smaller than the bore, of the tube orbarrel operated in the bore and having an apron operating through saidmouth, a keeper adjustably secured to one end of said housing and uponwhich the tube or barrel is oscillated, a keeper secured upon the insideof the barrel, and a spring inclosed by forth.

at. The combination with the housing havin g a longitudinal bore, amouth opening from said bore smaller than the latter, of the tube orbarrel operated in the bore, the apron operated through the mouth, thekeeper secured to and closing one end of the said bore and forming abearing for the said tube or barrel, a similar keeper secured in thebarrel, and a spring adj ustably secured in the barrel by said keepers,as set forth.

5. In a Weather-strip, the combination of the housing, With the barrelhaving an apron provided With a slot, the keeper secured to the housingand having a flange inclosing one end of the barrel and engaging saidslot, and a spring having one end attached to the keeper and the otherend connected to the barrel, as set forth.

In Witness whereof I hereunto set my hand in the presence of twoWitnesses.
